v and readily reversing the panel or inner portion by simple manipulation of the frame as by expansion or contraction of the latter.

The device permits of a great many uses for display and advertising purposes and will also be found available as a novelty, toy, or the like. For example, it is possible to place related pictures on opposite sides of the panel and cause display of the same in rapid sequence by reversal of the panel.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawing- Figure 1 is a view in perspective; and Fig. 2 is a similar view, showing the frame elongated and the panel reversed.

As shown in the drawing, the device is made out of a single rectangular sheet of stiff paper I with a rectangular panel or inner portion Illa partially severed therefrom by cuts II and I2 at the top and bottom, thus leaving the frame portion Illb around said panel.

The inner portion I0a remains attached to the frame I Gb by opposite ears I3, I3 at the sides. The frame portion is provided with oppositely bent folds across the same adjacent said ears. One of these folds is indicated by the dotted lines I5 and the other, by the dotted lines I6. It will be seen that each of these folds extends entirely across the frame I 0h and is interrupted by the inner portion Illa.

It will be seen that with the folds I5 and I6 bent as shown in Fig. 1, the panel IIJa will expose its reverse side and that when the frame is elongated to straighten the folds, as shown in Fig. 2, the panel I0*L will be reversed. Contrariwise, 5 the upper and lower ends of the frame may be pushed toward each other to again contract the frame and cause the folds I5 and I6 to bend to again reverse the panel I0a and place the device in the position shown in Fig. 1. When paper of suitable thickness and stiffness is used and the creases, folds or bends I5 and I6 properly made or creased, it will be found that by vertically elongating and contracting the frame portion Ib, the panel I0a may be rapidly reversed to l5 alternately expose first one side and then the other.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in view of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:

l. A piece of sheet material including, a frame portion and an inner portion attached thereto by opposite ears, the frame portion having oppositely bent folds across the same adjacent said ears, whereby said frame may be elongated to straighten said folds and reverse said inner portion. 1'

2. A device as claimed in claim 1, formed of a single sheet of material, the inner portion being severed from the frame portion, except where joined thereto by said ears.
